Qi Compliant Wireless Charging Solution boosts efficiency and reverse power transfer

With increasing demand for more power and higher efficiency,  STWLC68 product family provides the solution for wireless-charging applications with industry-leading efficiency, high power transfer and safety. ST’s newest wireless-charging products operate as both a high-power receiver and a transmitter enabling rapid power transfer and power sharing with FOD (Foreign Object Detection) and other important ST-proprietary safety IPs.
ST’s proprietary high-voltage technology, paired with excellent mixed signal design and highest quality assurance, enables our customers to deliver cutting-edge wireless-charging products. The STWLC68 family of highly integrated devices needs a very low external BoM (Bill of Materials), ideal for integration in a wide range of applications from small wearables and appliances to larger ones like smartphones and tablets. Being WPC Qi 1.2.4 compliant, the STWLC68 is fully compatible with all Qi certified devices in the market

Qi®-Compliant 15 W Multi-Coil Wireless Charger for Mobile Devices

STWBC-MC 15 W wireless battery-charger transmitter can control multiple charging coils, making charging less dependent on the precise position of the battery-powered device. Compliant with the latest Qi® 1.2.4 specification, the STWBC-MC is the first transmitter specifically designed to support the Qi MP-A15 EPP (Extended Power Profile) topology. In addition to detecting a valid receiver and selecting the most efficient coil for power transfer, it ensures extended Foreign Object Detection (FOD) through bi-directional communication with the receiver. The STWBC-MC also supports the proprietary wireless fast-charge extensions of leading smartphone manufacturers.
